- flowchart block scripting feels intuitive and flexible

- free tier allows 30 running blocks

- some blocks I've tried: send SMS, show toast, set clipboard, await motion gesture (finnicky), await volume button long press.

- it comes with an app inspector. Example usage: I wanted to make a shortcut for creating new notes. So I created a test note, activated the app inspector, and copied this output into an "app start" block:

  Package: com.automattic.simplenote
  Activity class: com.automattic.simplenote.NotesActivity
  Action: android.intent.action.SEND
  MIME type: text/plain
  Extras: {"android.intent.extra.SUBJECT": "test title", "android.intent.extra.TEXT": "content"}
